Do I need to increment the Room Database version number if I only changed the DAO's, not the entities?

Question

I was just wondering if you really need to increment the room database version number if you changed only the Data Access Objects (DAO's).

So the scenario is:

1. I already published the app in the Play Store with version x
2. I only changed part of some DAO's without changing the entities themselves
3. I incremented the app version code and name (maybe unrelated)

You need to increment the schema version when you change the schema. Simply adding functions to a DAO should not result in a schema change. However, your schema might change by things beyond your DAO and your entities. Right now, I think only @DatabaseView would have that effect in terms of annotations, and I do not see anything in RoomDatabase.Builder that should have an effect (other than addMigrations(), which specifically is for version number changes).
